My levels were all over the place TSH was low, T4 was going low too, GP thought maybe a pituitary problem. So I was finally referred to an endo consultant earlier this year, after two years of taking thyroxine.
He considered that I was 'NORMAL ' and my original levels were never below the blood test levels (I was borderline). His opinon - my GP had made a mistake, (bless her, she was treating me for the symptoms and looked at me as a whole person and not just a blood test number).
Follow Save Shares Saves Structure of Thyroxine (t) L-thyroxine is an oral thyroid replacement that's commonly marked under the brand names Cytomel, Levoxyl, Levothroid, Synthroid and Unithroid. L-thyroxine is used as a thyroid replacement therapy for people with hypothyroidism, which means that their thyroid gland does not secrete an adequate amount of thyroid hormones.
Hyperthyroidism may develop over several weeks and may persist for several months after therapy discontinuation. Amiodarone may induce hyperthyroidism by causing thyroiditis. Drugs that may decrease T4 absorption, which may result in hypothyroidism.
Additionally, prior to starting L-thyroxine, make your doctor aware of any preexisting medical conditions or allergies you have, particularly adrenal gland problems, diabetes and cardiovascular problems. It's worth noting that drugs like L-thyroxine are not intended to be used for weight control purposes.
Sympathomimetics Concurrent use may increase the effects of sympathomimetics or thyroid hormone. Thyroid hormones may increase the risk of coronary insufficiency when sympathomimetic agents are administered to patients with coronary artery disease.
I really don't want to go back on Thyroxine, I certainly improved when I first started taking the drug, however later on I went down hill even though I was taking 175 regularly.
The thyroid gland in dogs, as in humans, is responsible for producing hormones that regulate the proper metabolic function of the body's. The Side Effects of Thyroxine. L-thyroxine is an oral thyroid replacement that's commonly marked under the brand names Cytomel, Levoxyl, Levothroid,.
I read up on Synthroid's side effects and became concerned about the heart attack/disease issues. I am a 44 yo female and had a cardiac workup in March 2006 (blood tests, EKGs, Echo, 4 hr.

Seeing as the medication is a replacement therapy, many of the side effects serve as an indication that the dosage needs to be modified.
When a dog has low levels of natural thyroid hormones, a veterinarian. Levothyroxine is a medication that replaces a hormone normally produced by the thyroid gland to regulate metabolism and energy in the body.
Antidiabetic Agents - Biguanides - Meglitinides - Sulfonylureas - Thiazolidinediones - Insulin Addition of levothyroxine to antidiabetic or insulin therapy may result in increased antidiabetic agent or insulin requirements. Careful monitoring of diabetic control is recommended, especially when thyroid therapy is started, changed, or discontinued.
It should be noted that actions of particular beta-adrenergic antagonists may be impaired when the hypothyroid patient is converted to the euthyroid state. Short-term administration of large doses of glucocorticoids may decrease serum T3 concentrations by 30 with minimal change in serum T4 levels.
Antidepressants - Tricyclics (e.g., Amitriptyline) - Tetracyclics (e.g., Maprotiline) - Selective Serotonin Reuptake Inhibitors (SSRI s; e.g., Sertraline) Concurrent use of tri/tetracyclic antidepressants and levothyroxine may increase the therapeutic and toxic effects of both drugs, possibly due to increased receptor sensitivity to catecholamines.
Chloral Hydrate Diazepam Ethionamide Lovastatin Metoclopramide 6-Mercaptopurine Nitroprusside Para-aminosalicylate sodium Perphenazine Resorcinol (excessive topical use) Thiazide Diuretics These agents have been associated with thyroid hormone and/or TSH level alterations by various mechanisms.
Concomitant use of these agents impairs the compensatory increases in clotting factor synthesis. Prothrombin time should be carefully monitored in patients taking levothyroxine and oral anticoagulants and the dose of anticoagulant therapy adjusted accordingly.
An initial increase in serum FT4 is followed by return of FT4 to normal levels with sustained therapeutic serum salicylate concentrations, although total-T4 levels may decrease by as much as 30.
However, long-term glucocorticoid therapy may result in slightly decreased T3 and T4 levels due to decreased TBG production (see above). Miscellaneous Anticoagulants (oral) - Coumarin Derivatives - Indandione Derivatives Thyroid hormones appear to increase the catabolism of vitamin K-dependent clotting factors, thereby increasing the anticoagulant activity of oral anticoagulants.
Calcium carbonate may form an insoluble chelate with levothyroxine, and ferrous sulfate likely forms a ferric-thyroxine complex. Administer levothyroxine at least 4 hours apart from these agents. Patients treated concomitantly with orlistat and levothyroxine should be monitored for changes in thyroid function.
